At halftime of NBC’s Sunday Night Football last year, sports commentator Bob Costas addressed the topic of gun culture, and was drawn into a fiery debate. Costas addressed the issue again on “The Daily Show” and also waded into the growing controversy over football and safety. “Guns are glorified in hip hop culture,” Costas says at one point. “Some 70 percent of the players in the NFL are African American. Not all of them are influenced by that part of the culture, but some of them are.” Costas is a smart guy, but, for the record, hip-hop culture’s influence is now global and has been for decades, and isn’t just limited to the African-American community. And guns have been glorified in other music forms too, including country, blues and pop. Some of the songs that casual listeners may see as celebrating firearms, like “Me and My Girlfriend” by Tupac Shakur or “Saturday Night Special” by Conway Twitty, are often doing something more complex. Anyway, watch the clips of Costas’ comments. What do you think?
